  • Multiple NFC card applications in multiple execution environments
    Patent number: 9439220
    Abstract: A contactless system is described in which multiple execution environments may be coupled to a near field communication (NFC) controller, wherein each execution environment is configured to communicate with remote readers via the NFC controller using an assigned one of a plurality of communication protocols. During a polling session from a proximate reader, responding to a request command using a requested communication protocol and activating one of the plurality of execution environments assigned to the requested communication protocol to use the NFC controller. An arbitration is performed in response to each polling session such that a same combination of communication protocol and execution environment is not activated for adjacent polling sessions.
    Type: Grant
